1.3

Product description

The Daniel Senior Orifice Fitting is an orifice plate holding device that houses, and

accurately positions, an orifice plate within a pipe or tube to measure fluid flow. It is one

component of a flow measurement system. The Senior Orifice Fitting (Senior) is designed

to:

• Position an orifice plate, concentric to flow moving through a pipeline, within API

-14.3, Part 2 or ISO 5167 installation requirements.

• Allow personnel to remove and replace an orifice plate without disturbing the flow

measurement system piping, with little, or no, interruption in service and without

removing the Senior from the system.

The orifice plate within a Senior restricts the fluid moving through a pipe. This restriction

creates a change in static pipe pressure of the fluid. Instrumentation measure the

difference in change of the fluid entering orifice plate bore, and once again after it exits the

Introduction

plate bore. This instrumentation then combines that information, along with other data

gathered from the flowing fluid, and calculates the amount of fluid that passes through

the system.

The first chamber, or Body (4), properly positions the orifice plate in the flow stream. The

second chamber, or Top (14), is a temporary holding place for the orifice plate during

removing or installing operations (Refer to Section 4.2).

Important

The unit components have part numbers assigned on appropriate drawings and tables. Refer to

Figure 1-2 and Table 1-4 for part numbers. Example: Body (4).

Daniel Senior Orifice Fitting - Flangnek optionFigure 1-1:

Therefore, using a Senior may eliminate the need for bypass piping, valves, and other

fittings necessary with conventional orifice fitting installations. Maintenance technicians

can replace and repair all parts of the Senior, including the slide valve assembly, without

removing the Body (4) from the line (refer to Section .6).

Emerson designs and manufactures all Senior units to applicable API-14.3

recommendations and in accordance with selected ANSI, ASME and ASTM specifications.

As an option, Emerson Process Management also designs and manufactures fittings in

compliance with ISO 5167.

Products bearing the "CE" mark are designed and manufactured in compliance with the

European Union Pressure Equipment Directive (PED) 97/23/EC (available on the internet).

Refer to the "Daniel Orifice Fittings Installation and Operating Instructions specific to the

Pressure Equipment Directive", Part Number 3-9008-002 (available on the Emerson

Process Management website).

Conditions and specifications (continued)Table 1-2:

Maintenance in-

tervals:

The owners and users of these products should perform regular scheduled in-

tervals of maintenance activities. The recommended intervals are every month

or as directed by the owner's maintenance procedures. Examine components

during each scheduled maintenance period, site visits and during each orifice

plate change.

Replace any component that shows signs of wear or when damaged with parts

specified for Daniel products.

Seal replacement: Examine seals during each scheduled maintenance period, site visits and dur-

ing each orifice plate change.

Replace any worn or damaged or non-functioning seals with parts specified for

Daniel product.

Fastener torque

verification:

Check all fasteners for tightness during each scheduled maintenance period,

site visits and during each orifice plate change.

Use information provided in Section 5.3 as a starting point in establishing the

proper fastener torque values for your particular service environment.

Corrosion allow-

ance:

Emerson machines the meter bore of each fitting to close tolerances. This is to

conform to industry measurement standards.

The fitting's meter bore dimensions DO NOT include an allowance for corro-

sion.

It is the end user's responsibility to specify a fitting's material of construction

based upon their knowledge of the process fluid and environmental conditions

of an intended service.

Therefore, it is important that the end user to monitor any change in the gas or

liquid composition during monthly exercises, site visits and plate changes that

may create a corrosion concern (Reference: U.S. DOT, CFR Title 49: Part

192.477).

Environmental parameters:

Application: Surface and offshore (not for use in subsea applications)

Confined/open: Designed for outdoor use. May be used in well ventilated spaces (buildings/en-

closed meter houses). Installation at product owner's discretion.

Site temperature: Recommended atmospheric temperature ranges

Maximum: +120 °F (+49 °C),

Minimum: -20 °F (-29 °C).

Site humidity: No limit

Site elevation: No limit

Proximity to pop-

ulation:

Reference: Class 1 location: U.S. DOT, CFR Title 49: Part 192.5.

Proximity to traf-

fic:

The owner must protect the fitting from accidental damage by vehicular traffic

or other causes, by either placing the unit at a safe distance from the traffic, or

installing barricades around the unit.

Proximity to

equipment:

Install the Senior in a well ventilated place, not less than 3 feet (914 millime-

ters) from any source of ignition or any source of heat which might damage

the unit.

Interface parameters:

Conditions and specifications (continued)Table 1-2:

Replacement

parts:

Use only replacement parts specified for Daniel products. Unauthorized parts

and procedures can affect this product's performance and place the safe oper-

ation of your process at risk.

Aftermarket at-

tachments:

Use of pressure sensing equipment, drain valves, and other accessories (e.g.,

needle valves, multi-port valves, transmitters, 3-pin recorders… etc.) are per-

missible. The use of aftermarket equipment must be installed and operated as

directed by the after-market equipment manufacturer, and their warranties

and replacements are not contained within the scope of this document.

Pipe supports: The owner must employ sound engineering principles to design the support

systems for the flow measurement system (or meter tube).

It is important that the design engineer develop a method to support the en-

tire weight (equipment, piping and fluid) of the system.

The method developed must prevent bending to reduce the potential of creat-

ing unwanted stress at welded joints and flanges. Unwanted stresses may lead

to leaks and may ultimately lead to failure or rupture of the flow measurement

system.

Vandalism/Tam-

pering:

It is the responsibility of each product owner to protect the Senior from van-

dalism, tampering or other unauthorized activity.

(1) It is ultimately the responsibility of the Owner or End User to determine suitable materials of construction

suitable for a service conditions.
